Abstract
Retaining mechanism is forced the present invention relates to a kind of oblique core pulling of die casting.Including oblique core pulling oil cylinder and by the abnormity tiltedly core pulling of oblique core pulling hydraulic oil cylinder driving, latch segment is provided with the space of oblique core pulling oil cylinder end face formation corresponding with special-shaped tiltedly core pulling, latch segment two sides is contradicted on oblique core pulling oil cylinder and the abnormity tiltedly corresponding end face of core pulling respectively, and latch segment is entered within the space by latch segment hydraulic oil cylinder driving or from departing from the space.The present invention carries out pressure locking by latch segment to oblique core pulling, fundamentally solves sliding block card aluminium and core pulling retreats problem.Die Casting serialization, reduction mould upkeep cost and downtime, improving production efficiency are realized, the high-precision size requirement of die casting is reached；By actual verification：Since Die Casting workshop is used after this cover locking mechanism special-shaped oblique core pulling, there is not sliding block and retreated and sliding block stuck phenomenon again in the oblique core pulling of Die Casting Workshop, and Die Casting is stable, the upkeep cost reduction about 90% of this mechanism of mould.
Description
Technical field
Retaining mechanism is forced the present invention relates to a kind of oblique core pulling of die casting, belongs to die casting equipment technology field.
Background technology
Die casting has adapted to the complication of contemporary automotive parts product, precise treatment, lightweight requirements as a kind of advanced non-ferrous metal forming technique.Precise treatment and light-weighted requirement are to product wall thickness and profile tolerance requirement also constantly lifting.It is well known that Die Casting is a kind of high temperature, operations involving high pressure, in continuous Die Casting, due to high pressure, thermal expansion and accuracy of manufacture reason, product occurs that the overlap and sliding block of different situations retreat phenomenon.Overlap and sliding block are retreated generally can solve the problem that substantially by Making mold precision and cover half latch segment mechanism.But, for some special-shaped inclined holes with particular/special requirement of product（Groove）Mechanism, found because mould can not be designed when retaining mechanism can only carry out locking productions by oil cylinder self-locking and individual event valve, it is still obvious that the oblique core pulling of die abnormal-shaped retreats phenomenon, special-shaped core pulling groove card aluminium and sliding block retreat the serious of phenomenon and have had a strong impact on the oblique core pulling region contour precision of die casting and production stability, the upkeep cost of mould is largely increased, Customer Quality complains continuous lifting.
The content of the invention
The present invention is directed to drawbacks described above, it is therefore intended that provide a kind of simple in construction, the mechanism that can prevent oblique core-pulling slide block from retreating reduces production cost, retaining mechanism is forced in a kind of oblique core pulling of the die casting improved customer satisfaction.
It is for this technical solution adopted by the present invention：The present invention includes oblique core pulling oil cylinder（1）And by oblique core pulling oil cylinder（1）The abnormity tiltedly core pulling of driving（2）, the oblique core pulling oil cylinder（1）With special-shaped tiltedly core pulling（2）Latch segment is provided with the space of correspondence end face formation（3）, the latch segment（3）Two sides is contradicted in oblique core pulling oil cylinder respectively（1）With special-shaped tiltedly core pulling（2）On corresponding end face, the latch segment（3）By latch segment oil cylinder（4）It is driven within the space or from departing from the space.
The abnormity tiltedly core pulling（2）Inside it is provided with axially arranged oblique core pulling point cold（5）.
The special-shaped inclined shaft core（2）It is externally provided with oblique core pulling set（6）, the oblique core pulling set（6）With special-shaped tiltedly core pulling（2）And latch segment（2）The end face of contact is in same plane.
The abnormity tiltedly core pulling（2）With oblique core pulling set（6）Fit clearance is 0.02-0.05mm.
It is an advantage of the invention that：The present invention carries out pressure locking by latch segment to oblique core pulling, fundamentally solves sliding block card aluminium and core pulling retreats problem.Die Casting serialization, reduction mould upkeep cost and downtime, improving production efficiency are realized, the high-precision size requirement of die casting is reached；By actual verification：Since Die Casting workshop is used after this cover locking mechanism special-shaped oblique core pulling, there is not sliding block and retreated and sliding block stuck phenomenon again in the oblique core pulling of Die Casting Workshop, the upkeep cost reduction about 90% of stable this mechanism of moulds of Die Casting.
Brief description of the drawings
Fig. 1 is structural representation of the invention.
In figure 1 be oblique core pulling oil cylinder, 2 be special-shaped tiltedly core pulling, 3 be latch segment, 4 be latch segment oil cylinder, 5 be oblique core pulling point it is cold, 6 be oblique core pulling set.
Embodiment
The abnormity tiltedly core pulling 2 that the present invention drives including oblique core pulling oil cylinder 1 and by oblique core pulling oil cylinder 1, the oblique core pulling oil cylinder 1 and abnormity are provided with latch segment 3 within the space that tiltedly correspondence of core pulling 2 end face is formed, the two sides of latch segment 3 is contradicted on oblique core pulling oil cylinder 1 and abnormity tiltedly core pulling 2 corresponding end face respectively, and the latch segment 3 is driven within the space by latch segment oil cylinder 4 or from departing from the space.
Axially arranged oblique core pulling point cold 5 is provided with the oblique core pulling 2 of abnormity.
The special-shaped inclined shaft core 2 is externally provided with oblique core pulling set 6, and oblique core pulling set 6 and the abnormity end face that tiltedly core pulling 2 and latch segment 2 are contacted is in same plane.
Tiltedly core pulling 2 covers 6 fit clearances for 0.02-0.05mm to the abnormity with oblique core pulling.
The present invention the course of work be：1>Matched moulds：Oblique core pulling oil cylinder 1, which advances, reaches that into limit-latch segment oil cylinder 4 drives latch segment 3 to enter-locks special-shaped tiltedly core pulling 2- die casting machines and close up-injection；2>Die sinking：Latch segment oil cylinder 4 drive latch segment 3 move back-tiltedly core pulling oil cylinder 1 retreat and reach and move back limit-die casting machine die sinking-pickup.
The use of tiltedly core pulling set 6 of the invention, reduces Making mold difficulty, is easy to the control of fit precision, tiltedly core pulling 2 covers 6 fit clearances selection 0.02-0.05mm to abnormity with oblique core pulling, it is ensured that tiltedly core pulling 2 stuck will not there will not be overlap generation to abnormity.
